Protocols

Specificity / Sensitivity

Rab11FIP1 Antibody recognizes endogenous levels of total Rab11FIP1 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr188 of human Rab11FIP1 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Rab11 family proteins consist of closely-related Rab11a, Rab11b, and Rab25. They are small GTPases thought to play an essential role in regulating endocytic membrane traffic (1,2). The active state of GTP-bound Rab11 proteins interact with the Rab11 family interacting proteins (Rab11FIPs) via a conserved C-terminal Rab11-binding domain (3,4). At least six members of the Rab11FIPs have been identified. Based on sequence homology and domain structures, Rab11FIP1, Rab11FIP2 and Rab11FIP5 are categorized as class I subfamily members, whereas Rab11FIP3 and Rab11FIP4 belong to class II subfamily, which bind Arf6 and Rab11 proteins (5-7). Research studies have implicated Rab11 family proteins, and their interacting effectors, in carcinogenesis (8,9).
